STM32H743ZIT6,What is the maximum turnover frequency about GPIO with Timer?

[AASD.1]

I want to output 5MHz PWM as other chip CLK signal.How to do it?

It there are no other omitted details, use a TIMER in PWM mode (output compare channel).

Most GPIO have SPEED field and max toggling frequency maybe in the 50+ MHz range.

For the PWM frequency duty/period/step size, it's all about timer configuration. Usually NUCLEO-H7 SW example exists for TIMER with PWM output. Just remember that HAL do not provide API to change the PWM duty cycle (was not expected?), you write the TIMER HW registers directly or through the LL.

Well,but it seem it can not even reach 1MHz.

ON h743 port can up to 220MHz , at 11 power setting:
